William langland ( c.1330-1386), who wrote the long allegorical poem The Visions of piers Plowman; 威廉、兰格伦(约1330~1386),写有寓言长诗《把犁人皮尔斯的幻象》;
The tradition of allegory can be traced back to ancient Greek, but in the case of Anglo Saxon period, the tradition can be found in the works of Dante, Langland, Bunyan, Swift and George Orwell. 寓言诗的传统可以追溯到古希腊,但盎格鲁·撒克逊寓言诗的直接渊源在于《圣经》,与后来但丁、兰格兰德、班扬、奥威尔的寓言体作品一脉相承。
Three stages of medieval dream vision are exemplified by the dream poems written by Chaucer, Langland and others. 中世纪梦境叙述分为三个阶段,乔叟、兰格伦等的中世纪梦幻诗作为例证。
